Thanks for playing!
No, you really do just have everything from the start. It is a major problem that I genuinely have no idea how to approach other than just hoping players play around with it or tell each other how to use it lol
I do plan on completely reworking Louise in the near future, though, since my skills and knowledge have improved a lot since back when I first made her over a year ago. The concept will likely remain the same, just that the attack animations and general strategy will be reviewed.
